While the Covid-19 pandemic continues to rage more than a year after its appearance, every means of combating it should be considered with interest. Recently, a German glassmaker unveiled spectacle lenses incorporating an anti-microbial agent, a great first. It is about a treatment of glasses allowing them to overcome viruses and other microbes.
Since the arrival of the SARS-CoV-2 coronavirus, innovations are legion, although some may cause astonishment. Examples include the portable air purifier for small areas, the Covid test in a coffee capsule or the "antivirus mask" for vehicles. Recently, the German glassmaker ZEISS communicated on spectacle lenses with antiviral qualities. This is the DuraVision® AntiVirus Platinum UV treatment, advertised as being able to remove 99.9% of viruses and bacteria.
“Eyes are infection pathways for viruses and bacteria. In addition, the glasses that we handle all day long often without even noticing it can be infected by microbes that survive there for many hours. To address this issue, ZEISS has developed a new anti-reflective coating featuring an antimicrobial agent for the first time. , the company said.
Remember that glasses are an object that we handle regularly. In addition, the latter are particularly exposed to viruses because of their central position on the face. Also remember that the coronavirus is able to survive up to 72 hours on materials that often make up eyeglass frames, such as stainless steel and plastic.
After a collaboration with the Institute of Precision Medicine at the University of Furtwangen (Germany), ZEISS therefore presented its glasses capable of automatically eliminating viruses and other microbes . On the other hand, it is not a question of passing a product on the glasses. The latter have indeed directly undergone a treatment with the microbial agent , in addition to anti-reflective treatment.
The researchers injected concentrations of silver nanoparticles into the glasses. These particles possessing positively charged ions attack the negatively charged cell membrane of microorganisms. ZEISS took the opportunity to recall that the healing properties of silver have not been a secret for centuries for science and medicine. Finally, the German company begins to market its DuraVision ® anti-reflective lenses AntiVirus Platinum UV.
